INSOLE AND METHOD OF MAKING THE SAME.

Specification of Letters Patent.

Patented Jan. 11, 1921.

Application filed May 13, 1918. Serial No. 234,043.

To aZZ whom it may concern:

Be it known that I, FRANK C. Fix, a citizen of the United States, residing at C1nc1nnati, Hamilton county, Ohio, have invented a new and useful Improvement in Insoles and Methods of Making the Same, of which the following is a full, clear, and

exact description, reference being had to the This invention relates to an improvement in insoles and method of making the same, and more particularly to insoles in which the lip to which the welt is secured is formed of a piece of tape secured thereto.

This form of insole has gone into extensive use, due to the high cost of leather. A great many of these insoles are made of a composition of material having upper and lower layers of duck or canvas, which are secured thereto. The lip forming tape is secured to the bottom of the insole by stitching which extends through the tape and the entire, insole, so that the stitching, for securing the tape,:is exposed on the in; side of the shoe. This exposure of the stitching is objected to by some dealers, and I propose to overcome this objection without increasing the cost of the material.

I accomplish this by laying back a flap on the upper portion of the insole around the edge thereof and then securing the tape to the bottom of the insole by stitching through the body of the insole below the flap and the tape, and afterward cementing the flap into position to cover up the stitching. This flap may be formed along the entire surfacev above the tape, or the flap may merely be turned back along a portion of each of the sides so that the stitching at the front of the insole will extend through the entire insole;

The precise nature of my invention will" be best understood byreference to the accompanying drawings which will now be described, 1t being premised, however, that changes may be made without departing from the spirit and scope of my invention as defined in the appended claims.

Referring to the drawings, the reference character 2 designates the upper layer of duck, 3 the lower layer and 4 the intervening body portion between the two layers of duck. 5 designates the rib-forming tape secured to the under side of the insole by means of stitches 6. The insole is formed by first forming a flap 7 along the edge of the insole by turning back the upper layer of duck 2, as indicated in Figs. 1, 2 and 4, and stitching the tape 5 to the bottom thereof by passing the stitches through the body 4 and the. tape 5. After the tape has been secured to the insole, the flaps 7 are turned down and cemented to the body, as indicated in Fig. 5. In Fig.- 1 the flap is turned back around both sides of the insole as'well as at the toe portion, so that when the flap is pasted down, all of the stitches will be hidden. In Fig. 2 I have shown a construction in which the flap 7 is merely turned up along the portion of each side of the insole, the stitching from a to 5 extending through the body of the insole below the flap, while the stitching from b to Z) extends through the upper layer of duck, as well as the body of the insole. This is done by slitting the upper duck layer, as indicated at 8 in Fig. 2, and then stitching the tape in position. The flap is afterward turned down and cemented to the body of the insole.

The advantages of my invention result from the provision of an insole having a lip forming tape secured to the bottom thereof by means of stitches which extend through the major portion of the body of the insole and the tape, and are covered by means of a flap formed on the insole along the edge thereof and pasted in position over the stitching, together with the method of forming said insole.

I claim:

1. An insole having a lip forming tape secured to one side thereof by means of stitches, said stitches only extending through a portion of the insole and the tape along a portion of the length of the insole and covered by a flap formed on the insole and pasted thereto, the remainder of the stitching extending through the entirebody of the insole and the tape, substantially as described.

2. The method of making insoles, comprising forming a flat composition insole body having a fabric covering on the top thereof, turning back a portion of the covering along each side of the insole, and securing a lip-forming tape to the bottom of the insole by stitching through the insole and the tape below the turned back flap, and stitching through the entire insole at the front thereof, and then securing the side flaps over the adjacent stitching, substantially as described.

3. An insole having a lip-forming tape secured to one side thereof by means of stitches, said stitches extending through a portion of the insole and tape only along a portion of the length of the insole and covered by a flap formed on the insole and secured thereto, the remainder of the stitching extending through the entire body of the insole and the tape, substantially as described.

4. The method of making insoles, comprising forming a flat composition insole body having a fabric covering on one face thereof, loosening said cover throughout any desired portion of its length. and turning the same upwardly to form a flap, stitching a lip-forming tape to the opposite side of said body by stitching extending through said tape and body at one side of the flap, and then securing the flap over the stitching, substantially as described.

5. As an article of manufacture, an insole having a lip-attaching tape secured thereto by stitching, said stitching throughout a portion of its length extending only partially through the insole and throughout the remainder of its length extending entirely through the insole, substantially as described.

6. An insole having a lip-attaching tape secured thereto by stitching, said stitching alon the sides of the insole extending only 'partlally therethrough, and at the front thereof extending entirely therethrough, substantially as described.

7. As an article of manufacture, a composition insole having a fabric covering for one face thereof, a lip-attaching tape secured to said insole by stitching, said stitching throughout a portion of its length extending through the insole only and being protected by the covering, and throughout the remainder of its length extending entirely through the insole and covering, substantially as described.

In testimony whereof, I have hereunto set in hand.

y FRANK C. FIX.
